SPECIFICATION forming part of Letters Patent No. 430,953, dated J' une 24, 1890.

Application led March 25, 1890. Serial No. 345,242. (No model.)

.To a/ZZ whom t may concern.-

Be it known that I, HUGO HILL, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specification.

My invention consists in an improvement in oar-couplings, hereinafter fully described and claimed.

Figure l i`s a bottom plan view. Fig. :2 is a section on line oc, Fig. l; and Fig. 3 is an end elevation.

A represents the body of the car.

B O represent a device like apair of tongs, pivoted at K to any suitable support fastened to the car and terminating at the forward ends in the arrow-heads o c.

I represents a coil-spring connecting the rear ends of B and C and drawing them together.

H H represent stop-pins on the inner sides of the rear ends of B and O to steady the tongs B C.

D represents a double cam pivoted on the shaft L, secured to the car between the tongs B C forward of their pivot, and provided with a lever d, the end of which is connected by a chain R with the barrel of a windlass F, which windlass may be operated from the platform of a passen ger-car or from the top of a freightcar, or from the side of either a passenger or freight car, as desired.

E represents a ratchet-wheel on the barrel of windlass F, and. G represents a springpawl adapted to engage with the ratchetwheel E as the tongs B C are opened, and

`thus prevent the closing of said tongs.

J J represent two stop-pins playing through an iron plate N, secured to the under side of the car over the rear ends of the tongs B C, and normally pressed upward by the spiral springs j to permit the tongs B C to open freely.

S represents a metal plate having thereon two inclined surfaces t t, lying under the stoppins J J, and having an upturned end P,which passes through a slot n in plate N.

T represents a coil-spring which normally presses the plate S to the left, Fig. 2, so that it has no effect upon the pins J J.

o represents a chain secured to the upturned coupling the two cars together.

`end P of the plate N and terminating in a handle or ring M.

O represents a pin projecting from the under side of the car, upon which any length of the chain o may be hooked.

If' the plate S be drawn to the right, Fig. 2, the inclined planes t t thereon will press the stop-pins J J outwardly, causing them to project on either side of the tongs B O and prevent said tongs from opening or swinging.

The operation of my invention is as follows, and is clearly indicated by dotted lines in Fig. l: Assuming that two cars, each provided with the device herein illustrated, are to be coupled together, the arrow-heads b c are'left close together on one car, and on the other car are slightly separated, so that the inner surfaces of the separated arrow-heads will strike against the outer surfaces of the closed heads. The cars now being run together, the closed heads strike between and separate the slightlyseparated heads, as shown by dotted lines in Fig. l, and as soon as the heads have come together the inner shoulders on the separated heads spring behind the outer shoulders on the closed heads, The tongs B C, which are closed together, may be held rigid by drawing the plate S so as to project the stop-pins J J, the chain o being hooked over the pin O to retain said pins J J in projection. NVhen it is desired to uncouple said cars, the windlass F on the car which carries the open tongs B O is turned until said tongs open wide enough to disengage their arrow-heads from the arrow-heads of the tongs of the other car, in which position they are held by the ratchet-wheel E and pawl G. On Y IOO the two members of the tongsfsuhstantially as shown and described.

' 4. In a car-coupling,13he combination of the pivoted tongs B C With .the spring stop-pins J J' and sliding plate S, having thereon the inclined surfaces t substantially as shown 15 and described.

HUGO HILL.
